I'm aware of 120VDC 60mA current loops. The ASR-33 is 20mA @ 12VDC (or so). You are saying that the selector magnet in an ASR-32 pulls 60mA? -ethan

FYI, not much need to bother with the circuit boards. The meat of it (the teletype portion) is non-electronic and doesn't really depend on the boards at all. The phone part on the right was a Telex dialer, and it won't work with anything you can find today, short of possibly I-Telex. If you need help wiring, etc let me know as I have a 32 and can send pics. You'll need a loop supply capable of 60ma, which can even be a 12v supply just to shut it up while testing/running. Without a loop supply it'll chunk non-stop. Usually "proper" teletype loop supplies are around 120V DC though. Jeff G aka Bags

WTB: XT class 286 upgrade card
by Jason Perkins 02 Mar '20

02 Mar '20

Hi all, I'm looking to buy a 286 upgrade card... the kind that go into an ISA slot, and plug into the 8088 socket with a ribbon cable. Does anyone have one they'd like to sell? Thanks! -- Jason Perkins 313 355 0085

Data recovery of 8mm DAT tape (Sun Workstation)
by Jeffrey Brace 02 Mar '20

02 Mar '20

Someone asks: "I’ve 2-3 old 8mm DAT tapes from my sun workstation that I used to back up my sun workstations. I purchased a 8mm drive (along with a scsi controller, cables, etc) to read the stuff, but was only able to recover a bit of the data from them." Does someone have the hardware and/or knowledge to recover this for this individual? -- ========================================= Jeff Brace Vice President & Board Member, VCF East Showrunner Vintage Computer Federation http://www.vcfed.org/ jeffrey(a)vcfed.org

yet another retro source: thebrewingacademy.com/
by Jeffrey Jonas 02 Mar '20

02 Mar '20

I do not remember anyone mentioning this source of retrofits and retro-kits: https://thebrewingacademy.com/ for example: https://thebrewingacademy.com/products/texas-instruments-99-4a-flashrom-99 The Brewing Academy FR99: FlashROM 99 Cartridge for the Texas Instruments 99/4a $34.99 The Flash ROM Cartridge for Texas Instrument 99/4a , or FlashROM 99 for short, is a cartridge for the TI 99/4A home computer that allows for running ROM cartridge images stored on an SD card. The FlashROM 99 supports ROM-only images of up to 32K that use the write-to->60xx bank switching scheme. It will not work with programs using GROMs or CRU-based bank switching. The cartridge does not require the Peripheral Expansion Box and runs on both PAL and NTSC consoles. Apologies if this was already known. -- jeff jonas

GEOS 128 processor and SD card solution
by Jeffrey Brace 01 Mar '20

01 Mar '20

I'm researching use of GEOS 128. I've always been a C64 user and have used the C64 version of GEOS (Version 2). Does anyone know which processor is used by GEOS 128? Is it the 8502 or Z80? Also is there a uIEC that will work on a C128 *and* work with GEOS 128? I know that there was a bounty to make the uIEC work with GEOS 64. Thanks! -- ========================================= Jeff Brace Vice President & Board Member, VCF East Showrunner Vintage Computer Federation http://www.vcfed.org/ jeffrey(a)vcfed.org

Repair Workshop March 7 & 8 - Signup

01 Mar '20

The next repair workshop is next weekend. You can signup here: < https://docs.google.com/spreadsheets/d/1DySkGulduRUxJuPwK2RUEdP_yKD8YiDEn7K… > I'd love someone to assess the museum's SWTPC and the Heathkit H89. I have no idea if they are working and hesitant to just plug it in and turn it on, without assessing it's condition first. We are getting close to 100% of the machines in the museum working. -- ========================================= Jeff Brace Vice President & Board Member, VCF East Showrunner Vintage Computer Federation http://www.vcfed.org/ jeffrey(a)vcfed.org Access the Internet [image: QualityInnSuites] × User Agreement Close Welcome!
